To ALL WHOM l1r MAY' oon'eninvf p Be' it known that I, HENRY WANKLIN,of theUnited States revenue sten-mer Wilderness," have invented a new-and improved Saliuometer; 'and I do hereby declare that the following is a full, clear, and exa-ct description thereof', which will enable others skilled in Ithe'art to make and use the saine, reference being had to the accompanying drawings, forming part ot' this specification, in which ,hligure represents a verticalcentral-section ofthis invention.

This invention relates to a. salinonieterin 'which the gravity ofthe watervis determined by an ordinary sealebenm and weights, instead of by a hydrometer, as usual.` In the salinometer-pot is fitted, a piston, which works easily up and down,aud from the bottom ot' which extends a rod, which is hinged to one end of a scale-beam, the other end of which is so arranged thatit can beloaded withl suitable weights. It' the pot is filled with water from the boiler, the weight ofthe column ot` Wnter resting-on the piston can be determined, and by these means v l the'percentage of salt contained in the Water is observed.

A represents an ordinary salinometer-pot, which is boredout so as toreceive the piston B, which iitsfreely and works up and down quite easily. On the sides -of the cylinder-are fornied two charnbers, C D, which coininunicate with the interior Ofthecylinder throgh apertures a b. The chamber C formsthe'reeeiving-chamber, audit connects by a pipe, c, with'the water-space ot' the boiler. The water froth .the latter passes throngh the pipe e to the chamber C,froni which it flows to the salinometer-p'ot through the. opening a. VAn ordinary enel:

may be placed in the pipo e, at any suitable point, t opener close the communication between the salin'oineter and the boiler, so that the volume or quantity of lWater in theformer n iay be collected 'andiweighed independently oi' the water in the boiler. The chamber -D is theloveriiow or'nasteehauibeiythe waste-water being carried overboard, or to thebilge, by means et' the pipe d, A pipe, e,- extends from the bottom 'of the cylinder A to the waste-pipe d, and' through this pipe the water leaking past the piston iscaxjried off. Freni the under lside of the piston'f `extends a rod, E, through the cylinder-head, and this rod connects witlrthe short-arm ot n.

scale-beamLF, the long arm et'. which is so loaded with a weight. or weights, and so arranged that it sweeps over escale, G, wherebythe weightof the water pressing on the piston B, as indicated, may be determined.. By the' `proportion existing between the long and short arin of the scale-beam, a comparatively small motion oi"the .piston produces aA perceptible motion ofthefpointer attached te the long arm, and a slight change in the weight ot' the YWater can be readily observed. 1 v l ,The scale Gis indicated bynctual experiment, using sali-ne solutions of' gradually increasing strength, and as the specific gravity 'of the'water increases with Athe percentage ot' salt dissolved in it, the quantity of salt `contained in the water of tlie'b'o'ilercan bereadily-determined, without the use ot` a hydrometer or a.` thermometer.

It nlnet be remarked that,'inst end oi' the movable piston, a flexible or elastic diaphragm might be lised, which could be'connected to escale-beam or. to a pointer, by nieans similar to those used in steam-gauges, and a suitableiblonbl cock would carry oli' the falter after its specific gravity is' determined. v

'What Ilclaim as n'evrJand desire to secure `by Letters Patent, is* v 4 salinorneter, in which the specific gravity of the' water is determined orlmeasured, by its pressure/lon a .movable piStomsnbstautially'as and for the 'purpose set forth. n l

The above specification of my invention signed byrme, this23d day of February, 1866.
